Hitting and biting mom

So my son spends most of his time with me, making me the safest outlet. So he will occasionally hit or bite me, and rarely any one else. But what makes it worse is that he laughs when I scold him. We're trying to do time outs but haven't seen much progress. Any suggestions?

    Just keep consistently telling him no don't hit and give him something else to do, like reading a book or stuffed toy to put their energy into. I do that with my daughter and she hasn't hit me in awhile.

    I had my first child in April 2013, just before our one year anniversary. Riley has been an absolute joy and I love every minute of being mom. But I am the first among my friends to have a child, so there isn't always an easy place to go for advice.
